220kV智能变电站设计关键问题分析

Discussing Key Problems of Design for 220kV Intelligent Substation

针对智能变电站在信号采集和传输方式上的变革,使得其在设计方面与常规变电站有了较大的差异。在总结上海泸定智能变电站设计工作的基础上,针对智能变电站设计的特殊性,从二次系统入手,对智能变电站的设计特点进行分析和评估,并对设计关键问题进行剖析,提出解决方案以及应对措施,以期对今后建设智能变电站的二次设计、技术发展,提供经验与思路。

Based on intelligent substation reform in the signal acquisition and transmission mode, which at time of design for conventional stations have larger differences. On the basis of summing up the experiences of design Luding substation, this paper analyzes main characteristics of design from the secondary system; discusses some key technical problems, and the suggestions and solutions are also proposed, which can be available for reference in secondary system design for intelligent substation in the future.
